Dynamic Response of FGM Kirchhoff’s Plate

Abstract

The study proposes a new rectangular finite element of 16° of freedom based on hermitic cubic polynomials, for investigating the strength of a thin rectangular FG plate compared to conventional materials like pure ceramic or pure metals on the aspects of static and dynamic performance. A power law variation in material properties is assumed across the plate thickness. Mori–Tanaka homogenization scheme is employed for micromodeling of the FGM. A thin plate of particulate silicon carbide and aluminum matrix functionally graded composite is designed which is analyzed based on classical laminate plate theory and tested to clamped and cantilevered boundary conditions. The results are generated using MATLAB programming and validated using ANSYS commercial FEA package.
